Battery option for the tube.

[tubeN2]

Just remember: The NiCad batteries develope memory and eventually have a shorter life than the NiMh. Also when using the NiCad you have to completely drain the battery every time you use them before recharging. The NiMh have no memory and can be recharged at any state of useage.[]

One more key factor to consider!!!!! NiCad and NiMh are a 1.2volt battery therefore you will need to run 10 of those instead of 8 of the regular coppertops.
